vTo @ZZ whom/t it nea/y concern:

Be it known that I, HENRY C. HAM, a citizen;

of the United States, and'V al resident of -Liberty, in the countypf Union and State of 1n` diana, have invented-a certain new and useful of my specification.

My invention relates to force-feed seedingimachines of the classin which the seed is fed 4by means of a 1in-ted wheel revolving with a correspondingly-filmed rosette or rose-washer Ywhich prevents the escape of grain at its end, s with the usual cut-od1 forregulating the rate of feed for different grains.

The object of my invention is to providea combined rim and finte feed.v 4It is so constructed and arranged that when the liuted wheel is entirely out of the cup a rim-feed re v `mains for feeding a small.` amount of grain; but when the iutedv wheel is within the cup for feeding a larger amount of grain the rimfeed is combined with the flute-feed, so .as to produce a continuous feed and prevent the ob- Y jectionable bunching7 which has heretofore characterized the' flute-feed. Y. The `advantaggyes of'my construction will ap- 'pear more fully as I proceed with my specililn-the drawings, Figure l is a top plan View of a seed-cup to be attached to the bottom of a grain-hopper providedwith my improved feeding mechanism. Fig. 2` is a section of Fig. l on theline 2 2; and Fig.` 3" isa rear elevation, shown partly in section, on the line 3 3 of Fig. 2. Fig. 4 is a rear elevatiomshown partly in section, with the flute-wheel pushedv completely out of the cup.

A is the usual seed-cup, made in sections A' A, secured together by means of the lips a a, the whole cup being adapted to be attached to the bottom of a grain-hopper in the usual manner. i'

B is the lint-ed wheel, and C the sleeve, provided with the cut-olf gates D and E, both mounted on a slidable shaft inlany customary manner, so that the first is rotatable and the second fixed. i A

F is the rosette or rose-washer through which the fluted wheel B projects and in which it has bearing at .one end, as usual, having liutes to correspond with the ilutes of the liuted wheel. The rosette is provided with a shallow flange F', which at its inner edge is sharply inclined to the vertical. This inner inclined edge is provided with a number of Y short ribs f, which preferably correspond in number to the number of flutes on' the uted wheel. The rosette is provided with a boss f which fits in a corresponding recess on the inner' face ofthe section Af of' the seed-cup, in which it is held by means of a depending flange at the top of the section A' and by the inner edge of said section A at the bottom, vwhere it rises slightly above the bottom edge of the rosette, as seen at Z2', Fig. 3.

The inside edge :ofthe section A'of the seed-cup is provided with a flange c, which completely,7 covers the. outside edge of the rosette toward the bottom ofthe cup, but tapers off toward the top, so as to leave the outside rim of the rosette entirely uncovered at the top;

G is the lip of the grain-cup, over which the grain passes into the tube and is cut off Aflush with theoutside face of the gate E, so that no grain will collect behind it. E is slightly shorter than theV sleeve C by an amount equal to the depth of the flange on the rosette, nso that when the iiuted wheel B ispushed completely out of the cup, so as to have its inner end flush with the inner face of the rosette, aspace is left between the end of the gate E and the inner face ofthe rosette.

Vhen the parts are in this position, the mechanism feeds simply as a rim-feed, the ribs f elevating the grain and the inclination of the inner edge of the Harige causing the grain to be thrown over onto the gate E, from which it slips or slides into the grain-tube, this being made possible bythe fact that the lip G is flush with said gate.

The gate This feed is used when small grain is being sown. I/Vhen it is desired to sow larger grain or a greater quantity of the smaller grain, the finte-wheel B is drawn into the cup asuitable amount, in which case the flute-feed is combined with the rim-feed. The rim-feed acts in the same manner, as above described, in the case when the uted wheel is entirely out of the cup, and the flute-feed feeds the grain just as it does separately or when used by itself; but the two together work in such manner as to feed any desired amount of grain without any bunching, the rimfeed coperating with the flute-feed to produce that desired continuity of feed which the ordinary flute-feed lacks. I thus have the advantages of a rim-feed combined with those of the finte-feed, the two coperatingwitheach other to produce the desired result.

By having the outside rim of the rosette uncovered the grain resting on the top thereof is carried vdown into the bottom of the cup, and the provision of the tapering'flange c gives the grain a slight impetus toward the outlet, which greatly assists and facilitates the feeding `of the grain.

Having thus described my invention, what I desire to claim as new and to cover by Letters Patent is l. In a force-feed seeding-machine, in combination with a grain-cup and cut-off, a cornbined rim and iiute feed, the rim-feed being arranged to act, when the flute-is pushed completely out of the grain-cup, substantially as and for the purpose described.

2. In combination with the grain-cup, cutoffs and fluted wheel, a rose-Washer provided with a shallow ange sharply inclined to the vertical at its inner edge and having short ribs thereon, the gate of the cut-off terminating short of the inner end of the uted wheel, substantially as and for the purpose described.

3. In a force-feed seeding-machine, the combination with the seed-cup, of a force-feed4 seed-wheel, a rotating rose-washer provided with an inwardly-projecting ange, with the inner edge thereof sharply inclined to the vertical and having ribs and a cut-off gate terminating short of the end of the feeding-wheel, substantially as and for the purpose described.

4. In aforce-feed seeding-machine, the combination with the seed-cup, of av force-feed seed-wheel, a cut-off gate arranged to leave a space between it and the end of the feedwheel, and a revolving washer provided with a Harige sharply inclined to the vertical at its inner edge and having ribs thereon, substantially as and for the purpose described.

5. Ina force-feed seeding-machine, the combination with the seed-cup, of a force-feed seed-wheel, a cut-off gate arranged to leave a space between it and the end of the feedwheel, and a revolving Washer provided with a liange inclined to the vertical at its inner edge and having ribs thereon, substantially as and for the purpose described. p

6. In aforce-feed seeding-machine, the combination with the seed-cup, of' a force-feed seed-wheel, a cut-off gate arranged to leave a space between'it and the inner end of the feedwheel, said gate being Hush with the lip of the cup, and a revolving washer provided with a ange inclined at its inner edge and having ribs thereon, substantially as and for the purpose described.

7 In a force-feed seeding-machine, the combination with the grain-cup, cut-offs, and force-feed wheel, of a revolving washer of a diameter of substantially the depth of the cup, the upper edge of said washer being entirely uncovered and being in the plane of the upper edge of the grain-cup, substantially as and for the purpose described.

8. In combination with the grain-cup, cutoffs and force-feed wheel, a revolving washer suitably mounted in the grain-cup with its upper edge fiush with the top thereof, said cup being provided with a tapering flange, which covers the outer edge of said washer toward the outlet of the cup, substantially as and for the purpose described.

9. In a force-feed seeding-machine, the combination with the seed-"cup, of a force-feed seed-wheel, a cut-off gate arranged to leave a space between it and the inner end of the feedwheel and being in the plane of the lip of the seed-cup, and a revolving washer provided with a flange inclined at its Ainner edge and having ribs thereon, said washer having its top uncovered, substantially as and for the purpose described.

10. In a force-feed seeding-machine, in com.-l bination with the seed-'cup and lip thereof, and the force-feed seed-wheel and rose-washer, a cut-off gate terminating short of the inner end of the force-feed seedfwheel, its upper face being in the plane of the seed-cup lip, substantially as and for the purpose described.
